The comparison between SQL and NoSQL databases is really the comparison between relational and non-relational data structures. While most enterprises have found tremendous success using only SQL databases, many have also begun to integrate NoSQL databases. In this article, we’ll highlight the key distinctions between the two and why NoSQL is becoming a preferred solution for certain applications:
Key characteristics of SQL vs. NoSQL
First, let’s quickly review SQL databases. **S**tructured **Q**uery **L**anguage, is the standard language for relational databases. A relational database is characterized by its table-like structure with pre-determined columns and records organized as rows. Also known as a schema, the blueprint of a database describes the name, type, and constraints for each data field (column), as well as linkages across tables based on atomic data common to each. Relational databases draw strength from defined structures and the versatile query language to generate effective, reliable, and meaningful insight. Complex queries across tables can be produced using join and aggregation operations to perform computations and analytics. These powerful features make relational databases a great choice for Business Intelligence tools. However, there are also some drawbacks/challenges:
